Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7768, here are decompositions:

11 + 7757 = 7768
41 + 7727 = 7768
179 + 7589 = 7768
191 + 7577 = 7768
227 + 7541 = 7768
239 + 7529 = 7768
251 + 7517 = 7768
269 + 7499 = 7768

Showing the first eight; more decompositions exist.
